Mainland Resources Reports on Gas Flow for Haynesville Shale Well

Mainland Resources, Inc. Monday, March 16, 2009


Mainland Resources, Inc., a Nevada Corporation (the "Company") reports that management has received detailed data readings from its Griffith 11 #1 well provided by the operator showing total well flow through March 10, 2009.

The Griffith 11 #1 well located in Desoto Parish, Louisiana was completed and brought online in January 2009. The exact reading for total gas produced from the Haynesville shale and shipped to market through March 10, 2009 is reported at 568,856 MCF or .568 BCF.

Mainland Resources, Inc. holds a 40% working interest in the well and all future development in the Haynesville formation covering approximately 2695 net acres on its leases, which are located in northwest Louisiana.
The Haynesville Shale play is a new play less than one year old and there is limited data to work with to determine the decline rate for Haynesville Shale wells. The Company believes that the recoverable reserves for the Griffith well may ultimately be from 7.5 BCF to 15.81 BCF. The 15.81 BCF rate was determined by a reserve report for the Griffith #1 done by T.W. McQuire & Associates, Inc., prepared pursuant to U.S. Securities legislation. The ultimate recovery was determined by using a type curve that uses 80% decline for the first year, followed by 30% decline for the second year, 15% decline for the third year, and then a 10% decline over the remaining expected life of the well. This decline was derived from the Deutsche Bank report issued in 7/08 based on a study of various shale plays.
Mainland plans to participate in their second Haynesville well in Desoto Parish in May 2009. The third well on the Company's leases is on schedule to spud in August 2009.
Company President, Mike Newport states, "According to the data we received, this well has already produced in excess of a half a billion cubic feet of gas in forty (40) days from the Haynesville shale. Declines in pressure and daily gas production volumes are better than our expectations for the well."

Desotoguy, the well averaged over 14 million cubic feet per day (MMcfd) during those 40 days which is excellent. The well information is as follows and had an initial rate of 23.3 MMcfd:

Buy a map book called "The Roads Of Louisiana", you can google it or go to Shreveport to a big book store and find it. It cost a little less than 20 bucks but is a real good map book that shows section, township and range and damn near every pig trail in the state. I know they have it at Dixie Blueprint in Alexandria.

I know the Searcy boys at Dixie Blueprint in Alexandria have it and would sell it to you over the phone and get it into the mail that day on a credit card purchase. You don't have to worrie about doing biz with them cause their brother is an Assistant DA for Rapides Parish, I would highly recomend them.
